x = 7
3*x-6-(15)=0
3x - 21 = 3 • (x - 7)
Solve : 3 = 0
Solve : x-7 = 0
Add 7 to both sides of the equation :
x = 7
Answer:
-0.85714285714
Step-by-step explanation:
With a calculator or even by hand, you can divide the two numbers and find the solution. If you want to round up your answer is 0.86.
Hoping this answers your question!
Cos30 = square root of 3/2=0.8660
The cos of 60 is the sin of 30 n vice versa.
U can use the unit circle for this too
Answer:
x=34, y=-28, z=-46
Step-by-step explanation:
because opposite angles of parallelograms are congruent: -3y-3=81 => y=-28. because internal angles of quadrilateral sum to 360°: 81+-3(-28)-3+3x-3-2z+7=360 => 3x-2z=194 => z=3/2x-97. because opposite angles of parallelograms are congruent: -2z+7=3x-3. substitute z=3/2x-97: -2(3/2x-97)+7=3x-3 => x=34. z=3/2(34)-97=-46
Huh??? what does that mean
